Something about you!

  • Where do you come from?
  • What have you studied?
  • Motivation for the master?
  • Motivation for this course?!
  • Master project idea?
  • Post-master plans?

Course plan

Approximately half of the course will be focused on the basics of:

  • Hydrology: how rainfall becomes streamflow?
  • Hydraulics: how water moves in open channels and under pressure?

Before looking at two quite disctinct scenarios (in Norway):

  • Catchment scale flooding: how to deal with large-scale flooding?
  • Urban stormwater (SW) and flooding: how to best manage urbanized catchments?

Learning outcomes

Knowledge of:

  • the different components in the hydrological cycle and local water balance
  • the challenges and possibilities related to local runoff management
  • erosion and sediment transport in catchments and related mitigation measures
  • land use planning for local runoff management
  • potential impacts of climate change on water resources

Skills

  • Understand hydrological and hydraulics processes.
  • Make simple hydrological, hydrogeological and hydraulic calculations relevant to runoff management.
  • Use processes understanding to have a critical view on those calculations
  • Provide input for action plans and suggests solutions for local runoff management
  • Use different measuring techniques and carry out simple dimensional calculations of green infrastructure systems for urban runoff management
  • Use relevant computer software and GIS to identify flood-prone areas and potential problems arising from urban flooding and runoff

Teaching philosophy

“It is essential to see lectures as a means of helping students learn to think about the key concepts of a particular subject, rather than primarily as a means of transferring knowledge from instructor to student.”

Teaching philosophy

  • Open source text-based material (for collaboration), available online
  • Links to a lot of freely available material
  • Lots of questions to force thinking / active learning
  • Freedom to choose a variety of application projects

Given those course design choices:

  • Be active: take part in brainstorming exercises and questions
  • Be creative in your projects
  • Don’t hesitate to ask questions and reach for help
  • Give feedback: The course is a living document, please suggest improvements!

Soft skills: learning

Soft skills: work / life

Soft skills: leadership

HYDROLOGY

The water cycle

Lecture

We look at different components of the water cycle before diving into more detail.

Quiz

Hydrological processes

We will first discuss hydrological processes most relevant to hydrology in Norway: snow hydrology and vegetation processes: Lecture

We then cover groundwater, soil water and runoff generation which are important for the design of green stormwater infrastructure: Lecture

The quiz focuses on the impact of forest on water resources: Quiz

Hydrological extremes

Lecture

Quantifying floods and droughts helps better designing protection / adaptation measures.

Hydrological modelling

Lecture

Being able to model streamflow helps make better management decisions such as sizing of reservoirs, culverts or allowances for irrigation. We will look at different modelling concepts used in hydrology, their data requirements, forecasting abilities and limitations.

HYDRAULICS

Fluid dynamics

Lecture

We will look at water in pressure pipes. This is usually the domain of drinking water only but in somes instances, SW will have to be pumped out of a depression. Alternatively, SW could be used in off-grid design for micro-hydropower production or gravity fed irrigation schemes.

Open channel hydraulics

Lecture

How much flow can an open channel convey? How high will the water level be for a specifc discharge rate and slope? Those questions are important when sizing infrastructure or defining the extend of flood zones.

Soils, erosion and deposition

Lecture

Water can mobilize particules of various sizes. In extreme cases, boulders can be taken with the flow and form devastating debris flows. On the other hand, the smallest suspended particules are those that carry most pollution in SW runoff

Urban hydraulics

Lecture

We will try to summarize how hydrology and hydraulic come into play for the design of (green) SW infrastructure. this will involve simplified calculations for small catchments.

CATCHMENT SCALE FLOODING

Floodplain management

Lecture by Deborah Davies (HVL) on natural flood management.

We saw how precipitation led to runoff and how water level in channels varies as a function of discharge. Those results are used to produce flood zoning maps. We will now focus on the bigger picture of flood management in large catchments.

Flood protection works

Based on flood zoning maps and the quantification of hydrological extremes in specifc catchments, protection measures can be designed. Those consist of dikes, diverting channels.

This session consists of a full-day excursion with Svein Vågane from NVE Førde.

Land use

Lecture

We will see how alternative land uses may help mitigate catchment-scale flooding and erosion. Some agricultural practices could be applied in urban areas to link SW green infrastrure to local food production.

URBAN STORMWATER MANAGEMENT

Introduction to green SW infrastructure

Lecture by Kyrre Groven (Vestland Forskning)

We will look at the history of reticulated networks for SW and sewage. What are their limitations? Which pollution and flooding problems can be caused by sW runoff? Green SW infrastructure techniques will be introduced.

Green SW infrastructure

Lecture by Eli Heiberg (HVL)

Role of green infrastructure in urban storm water management:

Principles, measures and technology for local, open runoff management. We will also discuss the multifunctionality of green infrastructure

Quiz

Designing resilient infrastructure

Lecture

We look at some good and bad design examples and try to understand the reasons behing design choices and possibly unintended consequences / uses. Some examples focus on SW infrastructures but not all, in an effort to distinguish important design principles and constraints. This includes legibility. practicallity, multi-functionnality…

Suggested group projects

Design projects: Leikanger 100 dwellings, 10ha

Design projects: site map

Design projects: catchment

Design projects: options

Different groups could tackle different design challenges:

  • minimum extra outflow (least hydrological impact)
  • off the grid design
  • most agriculture / food production friendly design
  • design (incl. climate change) for its actual climate or
  • semi-arid climate (US mid-west, middle east)
  • mediteranean climate (Marseille, California)
  • (sub)tropical climate (NSW, central America)

Design projects: example drawings

Design projects: example drawings

Design projects: other ideas

  • You can suggest another area to be developed
  • Re-design the campus for water harvesting and irrigation of urban agriculture. This could be linked to smart reservoirs.
  • Look for problems involving SW in the region and propose solutions (dirt roads, specific locations in Sogndal)

Design projects: expectations

  • Drawings (hand, sketchup…) are encouraged.
  • Try to specify construction requirements: inputs / outputs in materials, timing
  • Explain the process: your assumptions, calculations, context, design choices…
  • Be creative: do not give only 1 option
  • No need for huge report

Synthesis projects

  • Recommendation for green infrastructure design in Norway: which techniques are promising, where, under which circumstances…
  • Prepare a set of reference drawings / specifications on stormwater management for Western Norway?
  • Develop a cheatsheet on green SW infrastructure (i.e nervous system, R programming)

Synthesis projects: expectations

  • Explanation of choices
  • Steal like an artist: build upon the resources synthesized
  • Neat and practical final product

Modelling projects

  • Data exploration and hydrological modelling of the Sogndal catchment using R
  • Flood frequency analysis for the catchment
  • Relationship between measured flow at Sogndalsvatn and flow in Sogndal (can be experimental too)

Modelling projects: expectations

  • Structured programs with R
  • Use of best practice for coding
  • Good explanation of the analysis: available data, methods, assumptions, results

Building projects

  • Design / Build a water pump or any other hydraulic feature (i.e ram pump). 2000 Kr available.

Expectations: similar to design projects + explain why it works as it does.

Experimental projects

  • Implement a data acquisition experiment in sogndal or in the Sogndal catchment. (available equipment: portable EC/pH meter, soil moisture sensors, soil temperature sensors, water pressure sensors, fluorometer)
  • Biochar properties: available water capacity, hydraulic conductivity, erodability…

Experimental projects

Repair and experiment with the fied infiltrometer and lab permeameter. This could include a review of infiltration measurement methods and improvement of this wikipedia article:

https://en.wikipedia.org/wiki/Infiltrometer

Experimental projects: expectations

  • Explain the why, what and how of experimental setup
  • Present results in a critical way: what went well and what didn’t

Social projects

  • Serious game development for stormwater management in Norway
  • Analyze the barriers to implementation of innovative SW practices in Norway.
  • Compare them with other countries
  • Compare them with other topics, for example composting toilets.
  • Discuss how crowd-based approaches could influence design / planning decisions (i.e. design of the campus)

Social projects: expectations

  • Have a scientific approach to the issue: what methods did you use, which assumptions did you make
  • High quality reporting

Project assessment

Project groups + second project

People Main project Second project
People project project2

Project development

  • Last 2 weeks of the course: project discussion instead of quiz
  • Every project gets 1-2h of everyone’s time: come with a short presentation of the project and first ideas.
  • Prepare good questions that the group can contribute to.
  • Animate the discussion.
  • During the 10 day period before the exam, every project gets a 2-hour block of my time.

Project reporting and presentation

  • The reports are sent to fkba@hvl.no and uploaded to fronter: Friday 9th of June. 24:00
  • Slide show of 5 minutes per person (so 15 or 20 min total depending on the group)
  • Videos could be part of the reporting, but not only
  • The group with the same “second project” as the presenters gets priority for questions. They should have read the “second project” report in detail.
  • The individual exam will then discuss the personal project, the second project and the course material

Exam details

  1. Written group project work (+ oral presentation). The group gets one common grading. If not approved, a new version of the project work must be handed in. Grading A-F.
  2. Individual in-depth oral discussion on the project work, the “second” project and finally some aspects of the course material (remembering the most difficult equations will not be required, but they should be qualitatively understood and you should have an idea on how to apply them). Grading A-F.
